Development of mixed-culture microbial granules under aerobic conditions in a sequencing batch reactor (SBR), capable of completely degrading a recalcitrant metal chelating agent is reported. In laboratory-scale reactor studies, the microbial granules degraded 2mM of free nitrilotriacetic acid (NTA) and Fe(III)-NTA completely in 14 and 40 h, respectively. Free NTA was degraded at a specific rat...
Microparticle drug delivery systems have been used for over 20 years to deliver a variety of drugs and therapeutics. However, effective microencapsulation of proteins has been limited by low encapsulation efficiencies, large required amounts of protein, and risk of protein denaturation. In this work, we have adapted a widely used immobilized metal affinity protein purification strategy to non-c...
Chelating agent is known as the enhancer for metal phytoextraction; however, there still a lack of efficient and environmentally sustainable chelators. Here, lemon residue extraction (LRE), prepared from 11 kinds fruit wastes, was combined with N, N-bis (carboxymethyl) glutamic acid (GLDA), tea saponin (T.S.) compounded plant-derived chelator (CPC), their influences on Cd phytoextraction by hyp...
